(p386) Journey of Excellence in Operating Non-recovery Stamp Charged Coke Oven Batteries at Tata Steel

摘要

The effort is being made worldwide to produce quality of coke to improve the blast furnace performance with a viewto reduce coke rate and improve productivity. Apart from impacting cost, this improves the CO2 footprints. This isfacilitated by proper selection of coke making technologies. The selection criteria of coals for different coke makingtechnologies and their operating conditions are the prime driver. Each technology has its own set of designobjectives to fulfil and primarily those are cost, quality of product and environmental impact. Recently, Tata Steelintroduced world largest single location annual capacity 1.6 MT of non-recovery coke plant. This paper describedthe operation philosophy of non-recovery coke plant to produce superior quality coke at comparatively lower costthrough operational excellence which includes reduction of imported prime hard coking coal in coal blend up to30% without sacrificing the quality of coke. Understanding the operation process and mastering non-recovery cokemaking technology was also part of this study.
